Description

Technical Field

[0001] The invention relates to the field of electric porcelain blank production, and in particular to a mud kneading device for producing electric porcelain blanks. Background Art

[0002] Insulators are ceramic materials used for electrical insulation and are widely used in power equipment, such as insulators, bushings, etc. In order to ensure that insulator products have good electrical properties and mechanical strength, special attention needs to be paid to the processing of insulator blanks. The slurry refining process of insulator blanks is one of the important steps in manufacturing high-quality insulator products, which requires processes such as raw material proportioning, wet and dry grinding, aging, dehydration and slurry refining.

[0003] However, most of the current electric porcelain blank mud refining devices use paddles to stir the mud to remove pores, and the staff needs to rely on experience to add water to the mud. However, the amount of water added to the mud is difficult to control, which can easily lead to too much or too little water added to the mud, affecting the viscosity of the mud. At the same time, simply stirring the mud is difficult to fully remove the pores in the mud, which will result in the quality of the subsequent electric porcelain blanks being poor.

[0026] Example 2

[0027] On the basis of Example 1, Figure 1-Figure 6As shown, it also includes a mud material extrusion component, which is arranged on the mud refining box 3. The mud material extrusion component includes a mud pressing plate 91. Two of the mud pressing plates 91 are slidably connected in the mud refining box 3.

The movement of the arc-shaped push frame 105 would drive the push plate 104 to move horizontally. The push plate 104 would push the water in the water tank 101 into the water dispersion plate 1031 through the two water pipes 103. The water would flow through the water dispersion plate 1031. 31 is sprayed onto the mud in the mud refining box 3. When the two guide chute frames 96 squeeze the two guide pillars 92 and move away from each other, one of the guide pillars 92 will drive the arc push frame 105 to move and reset in the direction away from the mud refining box 3. The reset of the arc push frame 105 will drive the push plate 104 to move horizontally in the opposite direction and reset. The reset of the push plate 104 will draw water from the water pipe into the water tank 101.
